1.	What does the magnetic field pattern inside the solenoid indicate ? State how this field be utilised to make an electromagnet. List two ways by which strength of this magnet can be increased.
Answer» It indicates that the magnetic field is same at all points inside the solenoid. This property is utilised to magnetise a piece of magnetic material like soft iron when placed inside the coil. Two ways by which the strength of an electromagnet can be increased : Increase the amount of electric current through it. Increase the number of turns of the coil.
